18 Claims. (Cl. 223-76) The present invention relates to new and usefulimprovements in boarding machines commonly used in the processing ofnylon and like hosiery. More particularly, the present invention relatesto improvements in machines of the type described in the U. S. patent toHeliot, Number 2,492,285 dated December 27, 1949.

In boarding machines of the type to which this invention relates, thestocking forms are arranged in three successive groups on a rotaryconveyor or turntable. Each group comprises a plurality of forms mountedin vertical planes and normally radiating from a vertical axis. Theforms in each group are loaded with stockings and are arranged to beenclosed successively by a vertically movable cover for treatment bypressure steam, or the like. As the stockings in each group are beingtreated, the stockings previously treated are removed from the forms inthat group and a fresh supply of untreated stockings is placed on thegroup of empty forms. To facilitate placement and removal of thestockings on the forms, each form in the group is pivotally mounted forhorizontal movement about a vertical axis so that adjacent forms may beswung apart on their pivots to provide ample work space for the removalof the stockings from each form.

With the circular arrangement of the patented device, there is room foronly one operator at a time to work at the forms in each group. Becauseof the time required, the operator must start stripping the stockingsfrom the forms as soon as they are uncovered. Consequently, the welts ofthe stockings which are ordinarily quite moist from the steam treatmentfrequently do not have time to dry completely before they are removedfrom the forms, and the operation must, therefore, be delayed. Inaddition, valuable time is lost when the operator must separate eachform from the remaining forms, and swing it into the desired workposition, at the same time swinging the previously loaded form out ofthe way.

With the foregoing in mind, a primary object of the invention is toprovide a novel construction and arrangement which affords greater speedin the removal and placement of stockings on the forms of a boardingmachine.

A further object of the invention is to provide an arrangement of theforms in each group on the turntable which permits greater utilizationof the space under the cover of the boarding machine.

More specifically, the invention contemplates a novel arrangement ofstocking forms on the turntable of the boarding machine which enablestwo operators to work at the stocking forms of each group on theturntable.

Another object is to provide a novel mounting means for the stockingforms in each group which operates to automatically position theindividual forms of the group in the most efiicient position forplacement and removal of the stockings on the form.

These and other objects of the invention and the various features anddetails of the construction and operation thereof are more fully setforth hereinafter with reference to the accompanying drawings, in which:

Fig. 8 is a plan view of a modified form of a mounting for the forms,within the scope of the present invention; and,

Fig. 9 is a front elevational view of the mounting illustrated in Fig.8.

The boarding machine illustrated in the drawings comprises a base 9having uprights 10 and 11 which mount a cover 12 for axial movement in avertical direction. Means is provided within the base to supply pressuresteam under the cover when it is in the lower position shown in Fig. l.The cover 12 is adapted to enclose a group of vertically disposedstocking forms which support the hosiery for setting treatment by steam.To this end, in the present instance, a plurality of forms 20 arearranged in three groups 21 on a rotary conveyor or turntable 22, eachgroup being mounted within an annular ring of the turntable. Theturntable comprises three such rings and rotates about the upright 11,so that each group is moved successively under the cover and enclosedthereby for treatment by the steam. To provide compactness and a highdegree of utilization of the space, the forms are mounted in spacedparallel alignment when the group is under the cover, but to provide foreasy removal and replacement of the articles on the forms, the forms maybe pivotally displaced from their paralel relation as is illustrated atlocation C in Figs.

Each stocking form 20 is mounted for pivotal movement about a verticalaxis. The form is integrally secured to a horizontal arm 24 which, inthe present instance, takes the form of a vertical base plate whichprojects laterally beyond the forward and rearward edges of the form asindicated at 25 and 26 respectively. The forward projection 25 isprovided with an offset flange 27 having an upturned lip which isadapted to bear against the next adjacent base plate to constitute aspacer element for the forms (see Figs. 1 to 3 inclusive). The rearwardprojection 26, on the other hand, is stamped out and turned back uponitself as illustrated in Figs. 3 and 4 to form a bifurcated mounting forthe vertically spaced axially aligned pivot studs 28 and 29. The upperand lower bifurcations define between them a recess 32, and the turnedback portion 30 is cut away from the recess 32 as indicated at 31 for apurpose set forth more fully hereinafter. The studs 28 and 29 arepivotally mounted in vertically aligned sockets 34 and 35 formed in acarrier defined by spaced horizontal carrier plates 36 and 37respectively.

In accordance with the invention, a cam element 40 is pivotally mountedon the stud 28 intermediate the carrier plate 36 and the upperbifurcation of the end plate 24. The cam 40 is formed as illustrated inFig. 6 having a central aperture 41, rearwardly converging cam surfaces42 and 43, and forwardly projecting lugs 44 and 45 which arespaced-apart, as illustarted, to define a recess 46. The aperture 41receives the stud 28, and the cam is positioned on the stud so that therecess 46 engages The lugs 44 and 45 extend forwardly whereby uponrelative pivotal movement of the form 20 and the cam 40, the lugs 44 and45 engage against the right and left faces respectively of the rearportion 26 of the end plate 24. It should be noted that the turned backportion 30 is cut back sufficiently at 31 to escape engagement with thelug 45 and thereby afford greater relative pivotal movement of the formand the cam.

The carrier plates 36 and 37 are rigidly joined to a carrier base 48 asindicated at 49. Each carrier base 48 is secured to and forms anintegral part of the turntable 22. As pointed out above, three groups offorms are mounted on the turntable 22, each group occupying a singlecarrier base 48.

In the embodiment illustrated in Figs. 1 to 6 inclusive, each group 21comprises two series of forms, 52 and 53 respectively (see Fig. 1). Thesockets 34 and 35 for each series are disposed in generally transversehorizontal alignment and the sockets 34 and 35 of the two seriesconverge forwardly and inwardly from the rearmost marginal portion ofthe carrier base 48 towards the central portion as illustrated in Fig.2. The turntable 22 includes also a fiat annular member 54concentrically disposed within each link of the turntable for sealingengagement with the cover 12. The member 54 underlies the two series incircumscribing relation thereto when the forms are in their normalspaced parallel position, as shown with reference to series 52 in Fig.2, so that when the cover 12 is sealed against the member 54, the formswill be enclosed by it. Means is provided in the base 9, to seal thelower end of the bell and to introduce steam at predetermined pressureand temperature into the chamber, as shown in the previously mentionedpatent.

In the operation of the device the turntable rotates clockwise to carryeach group of forms into locations A, B, and C successively, as seen inFigs. 1 and 2. After a group 21 of loaded stocking forms has beentreated by steam in location A, the cover 12 is elevated by mechanismWithin the central upright 11. In this respect it is noted that thepiping at the top of the cover is slidably engageable in a junction boxadjacent thereto as clearly illustrated in Fig. 1. The turntable 22 isthen rotated so as to shift the treated group 21 from location A tolocation B and to shift an untreated group from position C into locationA for treatment by the steam. During this treatment, previously treatedstockings which were dried in location B by the heat in the forms areremoved from the forms 20 in groups 52 and 53 in location C anduntreated stockings are placed on the empty forms.

When the stocking forms are moved from location A under the cover, theforms of both the series 52 and 53 are in the spaced parallel relationshown in connection with the series 52 in Fig. 2. After the articleshave been allowed to dry at location B, they are removed from the formsat location C. To this end, the first form in each series is pivotallydisplaced outwardly from the spacedaligned relationship shown, so as toafford ample room for the removal and placement of the stockings. Afteran untreated stocking has been placed on the form, the latter is pivotedon the studs 28 and 29 into engagement with an arm 57, described morefully hereinafter. The pivotal displacement of the form 20 causes therear end portion 26 of the form to engage against the lug 44 of the cam40 associated with the form, and the cam will be pivotally displacedwith the form 20. Upon pivotal movement of the cam, the cam surface 43engages against the cam surface 42 of the next adjacent cam. Theforcible engagement of the two cam surfaces causes the latter cam topivot counterclockwise about the stud 28 (see Fig.

Pivotal movement of this cam effects engagement of the lug 45 againstthe end portion 26 of its associated form 20 to thereby cause the latterto be pivotally displaced away from the succeeding forms in the series.Because of the limited lost motion between the cam and the form affordedby the inter-engagement of the recesses 46 and 32, the form may beadjusted to assume the most desirable angular position for removal andplacement of the stocking. After the untreated stocking is in place onthe form, the form is pivoted counterclockwise to engage against thespacer element 27 of the preceding form. This pivotal movement throughthe action of the cams will displace the next succeeding form to anangular position intermediate its two adjacent forms. The treatedstocking may then be removed from the form and an untreated articleplaced on the empty form.

By arranging the forms in two series, two operators are enabled to workon the forms in each group in location C, one operator Working on theforms in the series 52 and the other operator working on the forms inthe series 53. To insure against outward pivotal displacement of theforms as they are carried by the turntable 22 to a position underlyingthe cover 12, an arm 57 is provided at each side of the group of forms20. Each arm 57 is pivotally connected to the carrier base 48 at 56 andis biased to either the open position illustrated at 57a or the closedposition illustrated in broken lines 57b of a spring 58. The spring issecured at one end 59 to the carrier base 48 and is secured at the otherend 60 to the arm 57. The position of the attachment 60 is such thatwhen the arm is in the position 57a, it will be resiliently held in thatposition against a stop 61 by the spring. Pivotal displacement of thearm 57 will move the spring 61 over the pivotal center 56 of the arm sothat the spring 58 will bias the arm inwardly against the forms 20 asclearly illustrated at 57b in Fig. 2. Thus, when the forms have beenstripped and loaded, the arms 57, 57 are snapped inwardly so as to closethe forms to the spaced parallel position within the zone defined by theannular ring 54. After the stockings on the forms have been treated anddried and the group moved to location C, outward displacement of thefirst form in the series will snap the arm 57 outwardly to the position5711.

It is desirable that the form be held reasonably stationary as thearticles are removed and replaced. To this end, a brush element 63 issecured to the carrier base 48 so that its bristles extend upwardly intoengagement with the lower edge of the forms 20. The bristles beingrelatively stiff, will impede pivotal movement of the form so as to holdit reasonably steady while the articles are being removed and replaced.

A modified form of the invention is illustrated in Fig. 7 wherein aplurality of vertical stocking forms 65 corresponding to the group 21 ofthe forms 20 in the pre viously described embodiment are pivotallymounted in a plurality of transversely aligned sockets 66 in a carrier67. The carrier 67 is adapted to be mounted on a turntable (not shown)like the carrier defined by the elements 36, 37, and 48 in thepreviously described embodiment. Interposed between the carrier 67 andeach form 65 is a cam 68 identical in structure and function to the cam40 of the previously described embodiment. Arms 69, 69 are provided atthe opposite sides of the group of forms 65 and function similarly tothe arms 57, 57 of the first-described embodiment. In this modificationof the invention, there is room for only one operator to handle theforms in each group but otherwise the device functions identically withthe previously described embodiment, so that the forms are automaticallypivoted into the proper position for stripping and loading.

A further embodiment is illustrated in Figs. 8 and 9 wherein a pluralityof stocking forms 71 are pivotally mounted in aligned sockets 72 in acarrier 73, each corresponding to the similar element in the previouslydescribed embodiments. The sockets 72 may be in a single series like thesockets 66 or they may be in two converging series like the sockets 34and 35. To provide for automatic positioning of the forms for theremoval and replacement of the stockings, the forms are connected attheir outer ends by flexible ligaments, in the present instance, chains74. The chains are connected to the forms at the bottom of the endplates so that the chains do not interfere with the placement of thestockings on the forms. It will be apparent that as each form is pivotedin the socket 72 from the position indicated at 71a to the position 71b,the chain 74a will carry the forms 710 into the position 710. Because ofthe flexible character of the chain, it is possible to adjust theangular position of the form to the position found most desirable forthe removal and repllacement of the stockings, for example, as shown atWhile particular embodiments of the invention have been hereinillustrated and described, it is not intended to limit the invention tosuch disclosure, and changes and modifications may be made therein andthereto within the scope of the following claims.
